We report the characterization and formation of sonication-assisted liquid phase exfoliation of bulk black phosphorus (BP) crystals with the incorporation of two representative ionic liquids (ILs) ([Emim][Tf2N] and [Bmim][Tf2N]) as green dispersing media was attempted, which resulted in stable dispersion of multi-layer BP flakes with unsuspected high oxidation resistance and chemical/structural integrity due to the presence of IL layer on top of BP flakes. There are two unveiled issues for the generation of BP dispersion in ILs...

Prostate cancer (PC) treatment side-effects such as erectile dysfunction (ED) can impact men's quality of life (QoL), psychosocial and psycho-sexual adjustment. Masculinity (i.e., men's identity or sense of themselves as being a man) may also be linked to how men respond to PC treatment and ED however the exact nature of this link is unclear. This review aims to provide a snapshot of the current state of evidence regarding ED, masculinity and psychosocial impacts after PC treatment. Three databases (Medline/PsycINFO, CINHAL, and EMBASE) were searched January 1st 1980 to January 31st 2016...

BACKGROUND: Although polypharmacy is associated with significant morbidity, deprescribing can be challenging. In particular, clinicians express difficulty with their ability to deprescribe (i.e. reduce or stop medications that are potentially inappropriate). Evidence-based deprescribing guidelines are designed to help clinicians take action on reducing or stopping medications that may be causing more harm than benefit. OBJECTIVES: Determine if implementation of evidence-based guidelines increases self-efficacy for deprescribing proton pump inhibitor (PPI), benzodiazepine receptor agonist (BZRA) and antipsychotic (AP) drug classes...

Quanyu Wang, Zhuan Ji, Bo Han
Glycidyl fatty acid esters (GEs) are by-products of edible oil refinement that have attracted attention globally due to concerns over their possible harmful effects on human health when consumed. It is thus important to improve our understanding of GE formation if we are to suppress GE production during edible oil refinement. In this paper, a first-principles density functional theory study of the formation mechanism of GEs was performed. Triglycerides undergo a self-condensation reaction between two adjacent ester groups to yield GEs and an anhydride as a by-product...

INTRODUCTION: Self medication especially with analgesics is a common practice among undergraduate medical students. Variation in analgesic self medication prevalence and pattern is often seen due to geographical and target population differences. The mutual influence of pain and sleep quality might persuade students self medication behaviour. AIM: To assess analgesic self medication and its association with sleep quality among the medical undergraduates. MATERIALS AND METHODS: A cross-sectional questionnaire based study was conducted from December 2015 to February 2016 among 320 medical undergraduates...

Nanofibrils of small molecules, as a new class of biofunctional entities, exhibit emergent properties for controlling cell fates, but the relevant mechanism remains to be elucidated and the in vivo effect has yet to be examined. Here, we show that D-peptide nanofibrils, generated by enzyme-instructed self-assembly (EISA), pleiotropically activate extrinsic death signaling for selectively killing cancer cells. Catalyzed by alkaline phosphatases and formed in situ on cancer cells, D-peptide nanofibrils present autocrine proapoptotic ligands to their cognate receptors in a juxtacrine manner, as well as directly cluster the death receptors...

OBJECTIVE: Law enforcement officers tend to be exposed to a high frequency of potentially traumatic incidents. A dichotomous distinction among these events involves the witnessing of threat or harm to others and the experiencing of threat or harm directly to oneself. Past research suggests that different types of trauma exposure produce varying levels of negative posttraumatic responses including posttraumatic stress disorder (PTSD) symptoms and positive outcomes such as posttraumatic growth (PTG)...

BACKGROUND: Alzheimer's disease (AD), the most common disease causing dementia, is linked to increased mortality. However, the effect of antipsychotic use on specific causes of mortality has not yet been investigated thoroughly. METHODS: Utilizing the Danish nationwide registers, we defined a cohort of patients diagnosed with AD. Utilizing separate Cox regressions for specific causes of mortality, we investigated the effects of cumulative antipsychotic dosage after diagnosis and current antipsychotic exposure in the time period 2000-2011...

Objective: to identify and analyse children's voices in healthcare decision making in the discourse of Brazil's child protection laws. Method: Documentary normative analysis of Brazil's child protection legislation (1988-2012) based on the content analysis of nine texts, conducted in 2015. Results: The legislation acknowledges and stresses the voice of children in the decision-making process in research and healthcare. Any recognition of the right to dignity, liberty, information, and protection depends on what the adult decision-maker (with parental authority) believes is the child's capacity for discernment and whether the situation will cause self-harm...

Inflammation is the body's attempt at self-protection to remove harmful stimuli, including damaged cells, irritants, or pathogens and begin the healing process. In this study, strain-induced inflammation in pulmonary alveolar tissue under high tidal volume is investigated through a combination of an inflammation model and fluid structure interaction (FSI) analysis. A realistic three-dimensional organ model for alveolar sacs is built, and FSI is employed to evaluate strain distribution in alveolar tissue for different tidal volume (TV) values under the mechanical ventilation (MV) condition...

BACKGROUND: Since 2003, a harm reduction program for injecting drug users has been rolled out countrywide in China. It entails services for condom promotion, a needle and syringe program (NSP), and methadone maintenance treatment (MMT). However, it remains unknown if and to what extent the coverage of these services at city level is related to a reduced risk of HIV infection among drug users. METHODS: We wished to quantify the extent to which city-level characteristics (such as NSP and MMT service coverage) and individual-level determinants (e...

Chronotype is largely classified as being morning or evening types according to preference for daily activity and the preferred bedtime. This study examined the relationship between chronotype and temperament/character dimensions among university students. A total of 2857 participants completed the 140-item Temperament and Character Inventory-Revised Short version (TCI-RS) from a 5-score scale as well as the 13-item composite scale for morningness-eveningness (CSM). In this study, we classified chronotype as "morning," "neither," or "evening" types according to CSM scores and compared the scores in terms of 4 temperament dimensions and 3 character dimensions...

Cyberbullying has been portrayed as a rising 'epidemic' amongst children and adolescents. But does it create many new victims beyond those already bullied with traditional means (physical, relational)? Our aim was to determine whether cyberbullying creates uniquely new victims, and whether it has similar impact upon psychological and behavioral outcomes for adolescents, beyond those experienced by traditional victims. This study assessed 2745 pupils, aged 11-16, from UK secondary schools. Pupils completed an electronic survey that measured bullying involvement, self-esteem and behavioral problems...

BACKGROUND: Sexual difficulties (SD) are common among men of all ages and can have considerable impact on quality of life and indications for future health. SD are associated with mental and physical wellbeing and with relationship satisfaction, yet they are rarely discussed with medical professionals who are often ill equipped to assess and manage them. This paper provides an updated overview on the status of SD in Australian men from 18 to 55 years of age and will form a baseline comparison for future analyses of SD based on Ten to Men data...
